Modell: nike-241ijz; Availability :I Lager M = median (A,vecdim) computes the median based on the dimensions specified in the vector vecdim. For example, if A is a matrix, then median (A, [1 2]) is the median over all elements in A, since every element of a matrix is contained in the array slice defined by dimensions 1 and 2. example. median (MATLAB Functions) MATLAB Function Reference. median.

matlab program : 2d median filtering for salt and pepper noise without using medfilt2 function MEDIAN FILTER: In digital Image processing , removing the noise is one of the preprocessing techniques. Adaptive Filter MATLAB Design. An adaptive median filter performs spatial processing to reduce noise in an image. The filter compares each pixel in the image to the surrounding pixels. If one of the pixel values differ significantly from the majority of the surrounding pixels, the pixel is treated as noise. Matlab R2015a provide varied numeric computation methods to analyze data, prepare algorithms, and make models. Matlab R2015a is a high-level language and interactive.
For example, if A is a matrix, then median (A, [1 2]) is the median over all elements in A, since every element of a matrix is contained in the array slice defined by dimensions 1 and 2. example.

In this method, a window of specified length is moved over each channel, sample by sample, and the object computes the median of the data in the window. For more details, see Algorithms. To compute the moving median of the input: y = medfilt1 (x) applies a third-order one-dimensional median filter to the input vector, x. The function considers the signal to be 0 beyond the endpoints. The output, y, has the same length as x.
tsmedian = median (ts,Name,Value) specifies additional options when computing the median using one or more name-value pair arguments. For example, tsmedian = median (ts,'Quality',-99,'MissingData','remove') defines -99 as the missing sample quality code, and removes the missing samples before computing the median.
J = medfilt2 (I,[m n]) performs median filtering, where each output pixel contains the median value in the m -by- n neighborhood around the corresponding pixel in the input image. J = medfilt2 ( ___,padopt) controls how medfilt2 pads the image boundaries. This MATLAB function returns the mean of the elements of A along the first array dimension whose size does not equal 1. median(n) n can be any vector or matrix.
